On the share the name of the city is written with a w at the end. Ekaterinoslav, also known as Katerinoslav, Catherinoslav, or Yekaterinoslav, means "the glory of Catherine", referring to Empress Catherine the Great. This - at one time - 3rd largest city in Russia, after Moskow and St. Persburg, was founded in 1776 in what is now Oekraïne. In 1926 the name was changed to Dnepropetrovsk. It is a major city along de Djnepper river, with heavy industry, in Oekraïne.
Dnepropetrovsk was named after communist leader Grigory Petrovsky. As communist propaganda is forbidden by law since May 2015, the name of the city will be changed soon as well as all other places and streets the names of which refer to communist leaders.
Donetz was one of the 14 districts of the "Province" of Ekaterinoslav and also the name of a large city. The Donetz is a river (= smaller river Don) that ran through Donetz, I don't know why the factory was called Donetz as Donetz and Ekaterinoslav are located far apart. Perhaps it was a way of acknowledging that the steel industry was made posiible by the finding -in the late 19th century - of the Donetsk coal deposits and the Krivoy Rog iron ore, in an area called the Donetsk Basin. Anno 2015 these areas seek independance from or within Oekraïne. Dnepropetrovsk was "the closed rocket city" , unaccessable for foreighners from 1959 until 1987: it was the city where the Sovjet Union's ballistic missiles, rocket engines and the space industry flourished in secrecy.

Vignette: 5 by 5 cm. engraving
of the allegorical figure Virtus (Virtue) in harness, holding a
sword and a spear in her hands and treading down the allegorical
Tyranny, his crown fallen from his head; a broken chain and sword lying
next to him. Text: "SIC SEMPER TYRANNIS" (Engl.: Thus Always to
Tyrants; NL.: Zo gaat het
tirannen altijd), according to Bob Kerstein (www.Bob.com) the motto of
the
state of Virginia, wheras this allegorical figure of Virtue is
representing the spirit of the British Commonwealth, illustrting
struggle that has ended in complete victory. Hall, (1993, p. 78)
mentions that in Gothic sculpture a particular Virtue (there were quite
a number) often treads down the vice belonging to it. I invite those
who know more, to send me further comments on the correct
interpretation of this engraving. And, is there any reason why the
company would choose this vignette for it's stock ?
